It spends shock absorber part and forms cooperation, improve the adaptability shaken to different size to improve damping effect, while connector is set to mention
The cushioning ability of high second damping spring, the cushioning ability of the second damping spring is further increased with this.
Further preferably are as follows: the mounting plate offers mounting groove in the first vibration damper plate bottom end, and the connector includes logical
Cross several connecting shafts be rotatably arranged in mounting groove stick up bar, be rotatably dispose in each rotating block for sticking up bar both ends respectively and
With the support rod of one of rotating block rotation connection, second damping spring is mounted on other one piece of rotating block, described
Support rod and the second damping spring are slidably connected with the first vibration damper plate.
So set, first gradient shock absorber part can not play preferable cushioning effect, and when bearing significant shock
One damping spring is in the state of compression, can trigger the second gradient shock absorber part at this time, the support rod of connector can be second at this time
It moves down under the extruding of vibration damper plate, the second damping spring for being now placed in the other end can be moved up, final support rod and
Two damping springs can be abutted with the second vibration damper plate, at this time when support rod and the second damping spring are shaken, support rod and
Second damping spring can back and forth move up and down under the supporting role for sticking up bar to offset the vibration that the second vibration damper plate conducts,
So as to improve the cushioning ability of the second damping spring, so as to improve damping effect.
Further preferably are as follows: the mounting plate is provided with the first elastomeric spring, the described first elastic bullet in support rod bottom end
Spring top is connected with support rod bottom end.
So set, being resetted by the first elastomeric spring to support rod, and in support rod and the second damping spring
When being abutted with the second vibration damper plate, the first elastomeric spring under the supporting role of support rod, can generate limitation support rod on move down
On the one hand dynamic ability reduces the amplitude that support rod moves up and down, while under the compression of the first elastomeric spring, can have past up and down
The ability moved again, so as to improve the cushioning ability of support rod side, so as to improve damping effect.
Further preferably are as follows: the surface of the support rod is located in the first damping spring.
Further preferably are as follows: the support column to offset with the first vibration damper plate is provided in the mounting groove.
So set, being supported the first vibration damper plate by support column, prevent from causing first to subtract due to opening up mounting groove
Shake plate lower part can not stress and reduce the second vibration damper plate cushioning ability the case where.
Further preferably are as follows: the support column includes the cover board on support tube and top, is provided with and covers in the support tube
The second connected elastomeric spring of plate.
So set, the second elastomeric spring is provided with by support column, and it is identical as the first elastomeric spring effect, it can be improved
The cushioning ability of support column so as to improve the cushioning ability of whole device, and then improves damping effect.
Further preferably are as follows: the cover board top is provided with yielding rubber layer.
In conclusion the utility model having the beneficial effect that by the way that first gradient shock absorber part is arranged in contrast to the prior art
It is formed and is cooperated with the second gradient shock absorber part, when shaking smaller, damping is carried out by first gradient shock absorber part, at this time first gradient
The coefficient of elasticity of first damping spring of shock absorber part is smaller, can carry out damping by the elastic resilience of the first damping spring
Effect, avoids single damping device from shaking the situation of the damping effect difference of small vibration so as to improve to different size with this
Dynamic adaptability is to improve damping effect.
